EDWARD MOON, OF YOUNGSTOWN, NEW YORK.

COMBINED FIXTURE SUPPORT AND LOOM FASTENER.

Application filed `Tune 30, 1921. Serial No. 481,547.

l To all whom t may concern.'

Be it known that I, EDWARD W. MOON, a citizen of the United States, residing at Youngstown, in the county of Niagara and State of New York, have invented certain new and useful Improvements in Combined Fixture Supports and Loom Fasteners, of which the following is a specification.

My invention relates to a combined fixture support and loom fastener.

In a fixture support of the kind known as a crow foot, and which are in common use for attaching electric chandeliers to ceilings, noy provision is made for fastening the loom to prevent Withdrawal or displacement of the same. Consequently, short circuiting of the current will occasionally take place, -due to the displacement of the loom and contact of the current conducting wire passed therethrough with inflammable parts of a building.

One of the objects of my invention is to avoidthe possibility of short circuits and fires due to displacementV of the loom.

Another object of my invention is to modify the regulation crow foot employed for this purpose so as to enable the insertion of the loom through the base of the crow foot and the securing of the loom to the crow foot.

A still further object of my invention is to provide a combined fixture support and loom fastener wherein a comparatively large number of lengths of loom may be fastened in place to accommodatevwires leading to different bulbs or lights or different clusters of bulbs or lights.

.The invention consists in a fixture support having loom-receiving spaces or notches, and clamps for each loom or each pair of loo-ms, as the case may be.

The invention further consists in the novel features of construction and in the arrangement and combination of parts to be hereinafter described and more particularly pointed out in the subjoined claims.

In the drawings Fig. 1 is a vertical section through the divisional wall between two stories of a building, said wall including the flooring of the upper story and the ceiling of the lower story, the ceiling having my invention applied thereto and illustrated in connection with a portion of an electric chandelier.

Fig. 2 is an enlarged transverse section through the crow foot taken on line 2-2, Fig. 1, looking up.

Fig. 3 is a detached perspective view of the crow foot.

Fig. 4L is an enlarged vertical section through the crow foot and a portion of the ceiling taken on line H, Fig. 1.

Referring by numerals to the drawing,

the reference numeral 5 designates a pair of spaced joists, 6 the flooring, 7 the lath, and 8 the plaster. Connecting the two joists is a bridge piece 9 and fastened to each joist is a suitable insulation fitting 10, in each of which a length of loom 11 is clamped and through which looms, current-conducting wires 12 are passed which are adapted to be passed along or through an electric chandelier, designated for example in the drawing by the numeral 13.

14; designates the combined fixture support and loom clamp, generally referred to as a crow foot. It has preferably an annular base 15, an axial socket 16 internally threadedfas at 17, and legs 18 connecting said socket with the base.

Along the Ainner edge of the base between each leg and an adjacent leg 1S, loom-receiving notches 19 are formed, said notches being curved to conform to the shape of the loom 11 and serving as guides therefor. The loom is also guided by the peripheral face of the` socket 16, as best shown in Fig. 2. As shown, each base has six loom-receiving notches permitting the use of six lengths of loom7 and six individual lengths of currentconducting wires within said lengths of loom.

The base is provided with screw holes 20 through which screws 21 are passed that take into the ceiling and the bridge piece 9. The socket is provided with a number of tapped openings 22- intoon-e or more of which headed screws 23 may be threaded, the screws 23 having loom clamps 24 thereon formed of strips of metal curved to substantially conform to the central portion of the base 15 at the inner edge thereof between each two adjoining legs 18. Said loom clamps may be 'said to have concaved portions 25 near each end adapted to bear against the loom 11, and when tightening the screw 23 the loom fastener will be mov-ed inwardly and effectively clamp the loom between the loom-clamp 24 and the socket 16 of the crow foot. It will be apparent that a single length of loom may be clamped at one end of the loom fastener, the other end thereof moving' inwardly until stopped by the adjacent leg 18, which will serve as an abutA ment or stop for the same. p

When clamping a single length of loom at one end of a loom fastener, the screw 23 must be threaded into the socket 16 a considerably farther distance; the operation being the same as when clamping a length of loom at each end of the fastener. The loom of course extends from the insulation fittings 10 downwardly through openings in the `bridge piece 9 and through openings formed in the lath and plaster, and then eir-y tends downwardly along the inner edge of the base 15 of the crow foot and at a diametrcally opposite point along the. socket 16, it being clamped in the plane of the socket by the loom-clamp 24.

The 4,wires extending through the loom, which terminate preferably in or beneath the plane of the lower end of the socket 16, is then passed through or along the electric lchandelier 13 in any suitable manner, said fixture invariably having a cap 26 attached thereto, which surrounds the crow foot so as to completely conceal the same and the parts adjacent thereto.

While I have illustrated a crow foot with an annular' base 15, it is apparent that my invention may he applied to a modified form of crow foot, such for instance as have lugs extending from the upper ends of the legs for attachment to the ceiling, instead of continuing the metal of the support from one leg to the other. As this, however, forms no part of my invention and is Inerel7 another form of crow foot, (at one time in common use, but, now rejected as an impractical construction in certainterritories) my invention maynevertheless be applied to. e

crow foot of `such a type without departing from the spirit or sacrificing any ofthe advantages thereof, where the use of such a modified form is still permitted, or to any other form of fitting to be applied to a ceiling or wall.

In its broadest sense the base 15 may be considered a fastener portion, the socket 16 a supporting portion,'and the legs 18 connectoii portions whereby the supporting porchandelier is to be secured, means for fastening said cronT foot to a ceiling, legs connectlng saidmeans with saidsocket, and a loom clamp adjustablyV applied to said socket. Y

2. A iiXture-support, comprising a crow foot having an annular base, a socket coaxial with said base and legs connecting said socket with said base, a loom clamp beneath said base and between two of said legs, and a screw passed through said loom clamp and threaded into said socket,

3. A fixturefsupport, comprising a crow foot having an annular base provided with notches at its Vinneredge, a socket Coaxial with said base and legs connecting said socket with said base, and a loom clamp adjustably secured to said socket.

4. AiiXture-support, comprising an annular base, a socket co-aXial with said base and legs connecting said socket with said base, said base having a pair of spaced notches at its inner edge between two adjacent legs to permit the lpassage of looms between said base and socket, a loom clamp having concaved nortions conforming to the notches in said base, and a screw passed through said loom clamp between its concaved portions and threaded into said'socket.

5. SA lixtureLsupport, comprising a crow fQOt having an annular base with a notch therein conforming to the outline of loom, a socket for supporting an electric chandelier and suitable connectionbetween said socket and base, a loom Vclamp having a con-V caved portion conforming toV the shape of loom, and Ymeans' for adjustably securing said loom to said socket to fasten the loom between said clamp and socket.

In testimony whereof I. aiiixiny signature.
